Question

Suppose water is pouring into a cuboidal reservoir at the rate of 80 liters per minute. If the volume of
reservoir is 160 m3
, find the number of hours it will take to fill the reservoir.

Answer 1

1 meter cube = 1000lit
160 meter cube = 160*1000 lit = 160000 lit
water pour in reservoir In one min = 80lit

water pour in reservoir In one hour = 80*60 = 4800 lit

time required to fill reservoir of 160 meter cube= 160000/4800 = 33.33hrs
